Oli holds an NHS consultant post at University Hospitals Bristol, where he leads the St Michael's Endometriosis Centre (accredited by the British Society for Gynaecological Endoscopy). He is also a consultant fertility specialist at The Bristol Centre for Reproductive Medicine (BCRM, http://www.fertilitybristol.com). His private practice is conducted at The Spire Hospital in Bristol.

After qualifying from Imperial College School of Medicine he completed most of his junior training in obstetrics and gynaecology in the South West of England, before moving to the London and Oxford areas for specialist training.

He is particularly expert in the diagnosis (including ultrasound) and management of endometriosis and subfertility, although has a broad experience of all benign (non-cancerous) gynaecological problems.

He has published and presented (nationally and internationally) on many topics related to fertility, endometriosis and minimal access surgery, and is regularly invited to teach on courses. He is keenly involved in research and teaching (both at undergraduate and postgraduate level), and is active within the British Society for Gynaecological Endoscopy (BSGE); currently he is on the endometriosis centres subcommittee. He is a trustee of The Endometriosis Foundation (www.the endometriosis foundation.org).

Oli prides himself on collaborating to the highest level with both patients and colleagues to provide outstanding quality patient-centred care.
